Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment 1:
A kind of box beam precast pedestal with concrete wedge block, as shown in Figure 1, including pedestal ontology 1, in pedestal ontology
It is provided with pregroove marks 11 on 1, box girder formwork 2 is provided on pedestal ontology 1, is provided with wedge block template 3 in pregroove marks 11, and
Upper cystosepiment 4 is laid on 11 inner sidewall of pregroove marks, on the wedged template of concrete wedge block tensioning stress side.
With the rapid development of communication, driving is required at a high speed, steadily, comfortably, therefore, to Bridges on Highway knot
The continuity requirement of structure is very high, and slope design requirement, prefabricated case beam continuously hold general setting concrete wedge shape in length and breadth for bridge
Block adjusts vertical and horizontal gradient；But in formed by integrally casting box beam and concrete wedge block, in prefabricated case beam tensioning and it is detached from pregroove marks
When 11, concrete wedge block squeezes 11 inner sidewall of pregroove marks to along Impact direction, and the collision of concrete wedge block stress occurs
Damage, therefore, the side in pregroove marks 11, positioned at concrete wedge block tensioning stress are laid with upper cystosepiment 4, work as box girder tensioning
When stress arch camber, beam-ends (shape of soil wedge containing coagulation block) to centre shorten extruded foam plate 4, due to cystosepiment 4 elasticity modulus very
Small, although concrete wedge block is squeezed extruding force very little, and concrete wedge block will not go out under the protection of cystosepiment 4
Now cracking or the phenomenon that losing fangle, so that concrete wedge block be protected not to be damaged.
In order to which cystosepiment 4 to be fixed in wedge block template 3, as shown in Fig. 2, between cystosepiment 4 and wedge block template 3
Filling is equipped with Foam Expansion oxidant layer 41, in this way, cystosepiment 4 is bonded in wedge block template 3 by foam expansion agent.
In addition, since prefabricated case beam quantity is more, and the gradient of the concrete wedge block of its bottom is not quite similar, in reality
In construction, it is impossible to be gone to build pedestal ontology 1 according to the gradient of every kind of concrete wedge block, therefore, as shown in Fig. 2, wedge block
Template 3 includes the adjusting template 31 that inclination is set to 11 bottom of pregroove marks, and is provided at adjusting template 31 for controlling to adjust mould
The adjusting component 5 of 31 gradient of plate, meanwhile, the side template that fitting is set on 11 internal perisporium of pregroove marks is in 31 surrounding of adjusting template
32；Here, adjusting component 5 includes the bottom plate 51 set on 11 bottom of pregroove marks, is threaded on 51 4 jiaos of bottom plate and sets vertically
The adjusting bolt 52 set, four adjusting bolts 52, which support, is set to the setting of 31 bottom surface of adjusting template, and in adjusting template 31 and bottom plate 51
Between be filled with damp sand 53.
In this way, it is one group that two adjusting bolts 52 adjacent on bottom plate 51, which are divided, by adjusting two groups of adjusting bolts 52
Height is able to achieve the adjusting for exchanging section 31 gradient of template, and the damp sand 53 being set between adjusting template 31 and bottom plate 51 can match
The screw head for closing the adjusting bolt 52 being connected under adjusting template 31 plays supporting role, stable regulation template to adjusting template 31
31。
Embodiment 2:
The present embodiment is substantially the same with embodiment 1, the difference is that, in addition, since prefabricated case beam quantity is more, and
The gradient of the concrete wedge block of its bottom is not quite similar, in practice of construction, it is impossible to according to every kind of concrete wedge block
The gradient goes to build pedestal ontology 1, therefore, as shown in figure 3, wedge block template 3 includes the adjusting that inclination is set to 11 bottom of pregroove marks
Template 31, and as shown in figure 4, be provided with the adjusting component 5 for controlling to adjust 31 gradient of template at adjusting template 31, meanwhile,
The side template 32 that fitting is set on 11 internal perisporium of pregroove marks is in 31 surrounding of adjusting template；Here, adjusting component 5 includes top surface
The adjusting bracket 54 of smooth setting, here, 54 square frame shape of adjusting bracket setting, as shown in figure 5, in 54 both ends bottom of adjusting bracket
Two casings being parallel to each other 55 are welded with, rotation is inserted with cross bar 551 in every casing 55, and casing is stretched out at 551 both ends of cross bar
55 settings are connected with hound 552 at 551 both ends of cross bar separately down, and 552 bottom end of hound is connected with each other setting, even
The place of connecing is rotatably connected to adjusting rod 56 straight down, meanwhile, adjustment hole 511,56 screw thread of adjusting rod are provided in pregroove marks 11
It is connected in adjustment hole 511；As shown in fig. 6, the fitting of adjusting template 31 is placed in 54 top surface of adjusting bracket.In this way, being adjusted by rotation
Pole 56 drives cross bar 551 to be displaced in vertical mode, realizes the adjustment to 54 gradient of adjusting bracket.
In order to avoid the adjusting template 31 on adjusting bracket 54 slides, as shown in fig. 7, being provided with card on adjusting bracket 54
Block 541 is provided with card slot 311 in 31 bottom of adjusting template, and fixture block 541 is closely plugged in card slot 311.To utilize fixture block
541 fix 31 position of adjusting template with docking for card slot 311.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
